Job description
Company Overview ACS (Allen Control Systems) is a defense technology company building precision robotic systems for the United States and its allies. Founded by two former U.S. Navy electrical engineers with deep experience in robotics and software, ACS brings together AI, computer vision, precision motion, and advanced hardware to solve complex defense challenges across land, air, and maritime environments.
Our flagship product, Bullfrog, is an autonomous precision weapon system that transforms existing weapons into highly accurate counter-drone systems — giving warfighters a scalable, cost-effective response to one of the fastest-growing threats on the modern battlefield.
Job responsibilities
- Process high-volume AP invoices (150+ per week) in NetSuite, including PO and non-PO invoices, leveraging Ramp's AI-driven receipt matching, auto-coding, and policy enforcement to reduce manual data entry.
- Perform 3-way matching (purchase order, receiving/packing slip, invoice) to verify pricing, quantities, and terms;
- Manage corporate card spending through Mercury and employee reimbursements through Rippling; process weekly AP payment proposals, including ACH and wires, in line with vendor terms and cash flow schedules.
- Manage vendor inquiries and maintain strong working relationships with suppliers, freight carriers, and internal purchasing/engineering staff;
- Support month-end close by preparing AP accruals, running aging reports, and reconciling the AP sub-ledger to the GL; assist with vendor master file maintenance, including W-9 collection and 1099 tracking.
- Investigate and resolve invoice discrepancies related to freight, tooling, raw materials, components, and prototyping purchases; support audits by preparing documentation and responding to auditor requests.
Job requirements
- 3-5 years of high-volume, full-cycle accounts payable experience, ideally within a manufacturing, hardware, or industrial/technical environment;
- Hands-on experience with NetSuite (or a comparable ERP such as Odoo) for AP processing, vendor bill management, and reporting; experience with Ramp or similar spend management/corporate card platforms.
- Comfort adopting AI-based tools and automation, such as OCR invoice capture, auto-coding, and anomaly detection; proficiency in Microsoft Excel (VLOOKUPs, pivot tables).
- Solid understanding of GL coding, cost centers, and accrual concepts; excellent attention to detail, strong communication skills, and comfort operating in a fast-paced, evolving startup environment.
- Must be a U.S. Person (U.S. citizen, lawful permanent resident, or protected individual as defined by ITAR/EAR) due to export control regulations applicable to defense technology; ability to pass a background check.
